FIG. 1 depicts an illustrative embodiment of a first communication system 100 for delivering media content. The communication system 100 can represent an Internet Protocol Television (IPTV) broadcast media system. The IPTV media system can include a super head-end office (SHO) 110 with at least one super headend office server (SHS) 111 which receives media content from satellite and/or terrestrial communication systems. In the present context, media content can represent audio content, moving image content such as videos, still image content, or combinations thereof. The SHS server 111 can forward packets associated with the media content to video head-end servers (VHS) 114 via a network of video head-end offices (VHO) 112 according to a common multicast communication protocol.
The VHS 114 can distribute multimedia broadcast programs via an access network 118 to commercial and/or residential buildings 102 housing a gateway 104 (such as a common residential or commercial gateway). The access network 118 can represent a group of digital subscriber line access multiplexers (DSLAMs) located in a central office or a service area interface that provide broadband services over optical links or copper twisted pairs 119 to buildings 102. The gateway 104 can use common communication technology to distribute broadcast signals to media processors 106 such as Set-Top Boxes (STBs) which in turn present broadcast channels to media devices 108 such as computers or television sets managed in some instances by a media controller 107 (such as an infrared or RF remote control).
The gateway 104, the media processors 106, and media devices 108 can utilize tethered interface technologies (such as coaxial or phone line wiring) or can operate over a common wireless access protocol. With these interfaces, unicast communications can be invoked between the media processors 106 and subsystems of the IPTV media system for services such as video-on-demand (VoD), browsing an electronic programming guide (EPG), or other infrastructure services.
Some of the network elements of the IPTV media system can be coupled to one or more computing devices 130 a portion of which can operate as a web server for providing portal services over an Internet Service Provider (ISP) network 132 to wireline media devices 108 or wireless communication devices 116 by way of a wireless access base station 117 operating according to common wireless access protocols such as Wireless Fidelity (WiFi), or cellular communication technologies (such as GSM, CDMA, UMTS, WiMAX, Software Defined Radio or SDR, and so on).
Another distinct portion of the computing devices 130 can function as a media distribution device. In one embodiment, the distribution device 130 can be a mobile device capable of being positioned in proximity to a media event 199, such as a sports event, concert, studio and so forth. The mobility of the media distribution device 130 can be achieved in a number of ways, such as being positioned in a media truck and so forth. Although the present disclosure also contemplates the device 130 being a fixed device.
The media distribution device 130 can have a plurality of modules or servers that allow for receiving of the media content, encoding the media content into various desired formats, and distribution of the encoded media content over an IP network infrastructure to which the media distribution device can be operably coupled.
It will be appreciated by an artisan of ordinary skill in the art that a satellite broadcast television system can be used in place of the IPTV media system. In this embodiment, signals transmitted by a satellite 115 supplying media content can be intercepted by a common satellite dish receiver 131 coupled to the building 102. Modulated signals intercepted by the satellite dish receiver 131 can be submitted to the media processors 106 for generating broadcast channels which can be presented at the media devices 108. The media processors 106 can be equipped with a broadband port to the ISP network 132 to enable infrastructure services such as VoD and EPG described above.
In yet another embodiment, an analog or digital broadcast distribution system such as cable TV system 133 can be used in place of the IPTV media system described above. In this embodiment the cable TV system 133 can provide Internet, telephony, and interactive media services.
It follows from the above illustrations that the present disclosure can apply to any present or future interactive over-the-air or landline media content services. For instance, communication system 100 can employing an IP Multimedia Subsystem (IMS) network architecture to facilitate the combined services of circuit-switched and packet-switched systems for delivery of the media content from the computing devices 130.
FIG. 2 depicts an illustrative embodiment of a media distribution device 200 for delivering media content. One or more components of device 200 can be incorporated into media distribution device 130. Device 200 can include a modular chassis 205 that allows for removable connection of various components, modules or servers with the device. The particular connection structure used to provide for the removable connection as well as allow for communication between the various components can vary and can include an interconnect matrix. In one embodiment, the connection structure can be an I/O backplane 260 that provides for connectivity with each module for I/O and management connections. The I/O connections can vary, and can include SDI/HD-SDI/ASI, Ethernet and/or physical electrical connections. In one embodiment, the connection structure can provide for slideable mounting of the modules into the chassis so that the module is in communication with the other modules and is operable once slid into the chassis 205.
The device 200 can include a video server module 210 removably connectable with the chassis 205 for storage and distribution of static content. For example, the media content can be loaded via physical media storage or over network connectivity. A plurality of encoder modules 220 can be removably connectable with the chassis 205 for converting traditional video connections to encoded video for transportation over an IP network infrastructure. In one embodiment, ports can be provided for monitoring the video signal, such as through a monitor/passthru port. The video encoder modules 220 can encode the media content into various formats, including VC-1 and H.264.
In one embodiment, one or more of the video encoder modules 220 can be used for generating one or more lower profile versions of a main profile of the media content. The encoders 220 can embed code in the multiplex to develop lower profile copies. In one embodiment, the lower profile copies have lower resolution and higher error correction data, such as more FEC symbols in the data stream. In another embodiment, the main profile of the media content can be generated in MPEG-2 format while the lower profiles can be generated in H.264 and/or VC-1 format. The particular number of lower profile versions of the media content and the particular resolution and/or amount of error correction data can vary. In another embodiment, video scaling techniques can be employed so that the lower profile versions of the media content do not have a direct correlation to the MPEG-2 format of the main profile.
The device 200 can include an IP router module 230 that is removably connectable with the chassis 205. The IP router module 230 provides for connectivity to IP transport links, as well as out of band access for management of the chassis 205 and/or the other modules. The device 200 can include an IP switch module 240 that is removably connectable with the chassis 205. The IP switch module 240 can provide for connectivity to external Ethernet/IP hosts. This can allow for network connectivity to the modules as well. The device 200 can include a video monitoring module 250 that is removably connectable with the chassis 205. The video monitoring module 250 can monitor video quality and/or perform transport stream analysis. Various techniques can be utilized for the monitoring.
In one embodiment, the various modules can be replaced based on the desired distribution. For example, if the media content is intended only for distribution to hand held media devices then encoders 220 can be removably connected to the chassis 205 to provide for EVSB (Enhanced Vestigial Sideband modulation) encoding. For instance, signal processing can be applied by the encoders 220 according to an Advanced Television Systems Committee standard (ATSC), such as the mobile handheld standard, so that code is embedded in the multiplex which develops lower profile versions of the main profile. In one embodiment, the standard can be based on or related to the ATSC Recommended Practice: E-VSB Implementation Guidelines, document ATSC A/112, which is the ATSC standards related to E-VSB, and provides guidelines to parameter selection and implementation scenarios; the disclosure of which is incorporated herein by reference.
In another example, if the media content is intended for a broad distribution over various types of networks then encoders 220 can be removably connected to the chassis 205 which support each of those formats. Device 200 also allows for the modules to be easily replaced when an upgrade is available or when a failure has occurred. As another example, if a producer wants to distribute a single program via an IP network a set of modules that can be tailored to the producer's current needs can be deployed. If later that same producer wishes to increase the content that will be sent via IP transport a simple module change can facilitate the increase in encoder processors and network bandwidth via module interfaces.
FIG. 3 depicts an illustrative embodiment of a media distribution device 300 for delivering media content. One or more components of devices 130 and 200 can be incorporated into media distribution device 300. Device 300 can include the modular chassis 205 that allows for removable connection of various components, modules or servers with the device. The device 300 can include an IP router module, a video monitoring module, a video server module, an IP switch module and a plurality of video encoder modules which allow for distribution of a plurality of media contents over an IP network to various recipients (such as a central office, VHO and so forth). The device 300 can also include a network module, a content switch module, and A/D encoder module, a video synchronization module, an audio encoder module, an A/V test pattern module and/or a traffic module.
FIG. 4 depicts an illustrative embodiment of a communication system 400 having media distribution device 200 positioned therein. The device 200 can distribute different formats of the media content to various recipients, such as the set top box over the IP network and DRM server, as well as via satellite and so forth. The use of media distribution device 200 allows for real time distribution of the media content upon capture from the media event.
Device 200 allows use of an existing IP network to transport video content through out the world using dynamic routing protocols. Device 200 can provide both real time video content as well as static disk based content with the use of a single unit. Operational efficiencies can be achieved due to having only to manage one device.
FIG. 5 depicts an illustrative method 500 that operates in portions of the communication systems of FIGS. 1 and 4. Method 500 can begin with step 501 in which the mobile distribution device 200 is positioned in proximity to the media event. In step 502, the media content can be captured and then provided to the device 200, such as through the video server module 210. In step 504, it can be determined whether the desired modules are in place in the device 200, such as by determining the network destinations and/or the media formats most compatible with those destination or with transport to those destinations. This determination can be made by the technicians and/or can be made by the device 200. For instance, the device 200 can have an interface (not shown) for receiving information as to the media destinations. Based on this information, the device 200 can present the types of modules that should be placed in the chassis 205.
If the desired modules are not positioned in the chassis 205 then in step 506 the desired modules can be positioned therein including being placed in communication with one or more of the other modules so that the distribution of the media content can be implemented. In step 508, the desired video formats can be generated using a plurality of video encoders 220. The particular number of formats and the type can vary based on a number of factors, such as the desired destination of the media content.
In step 510, the IP router module can route the plurality of media contents to their desired destinations over an IP network infrastructure. The distribution device 200 can be removably coupled to the IP network using various connection devices and/or wireless interfaces. The particular routing scheme and techniques can vary. For example, the plurality of media contents can be bundled together and routed to a single destination where the media contents are then separated and further distributed. In another embodiment, the various distinct formats of the media content can be separately distributed over the IP network to various different locations, such as a central office for broadcast to set top boxes and to a VHO for broadcast over an IPTV network infrastructure, including via satellite.
In step 512, the video quality and/or the transport stream can be monitored for faults and corrections can be applied, such as through module 250. In one embodiment, the module 250 can determine if the link, such as the PID lock, is in jeopardy of being lost or otherwise losing synchronization or continuity of the video. If the link is in jeopardy then the module 230 can provide the viewers with a lower profile version of the media content which has a lower resolution but higher error correction data in order to maintain the link. The particular error correction technique utilized can vary and can include FEC, such as block coding, convolution coding, concatenate coding, turbo coding and so forth. The above-described switching to lower profiles to be transmitted can be performed at the device 200 and/or at an intermediary server, such as at a VHO. The link being monitored can be with the viewer's media device, such as a hand held device, and/or can be with a provider distribution device, such as at the VHO.
In one embodiment, the device 200 can determine which of a group of lower profile versions of the media content should be distributed. The various lower profile versions can be stored by the device, such as at video server module 210. The determination can be based on a number of factors, including the amount of faults and/or the type of faults detected which jeopardize the video continuity.
Upon reviewing the aforementioned embodiments, it would be evident to an artisan with ordinary skill in the art that said embodiments can be modified, reduced, or enhanced without departing from the scope and spirit of the claims described below. For example, the video server module 210 can be the controller for the device 200. Control signals from the module 210 can be sent to the various other modules to actuate their respective functions, such as commencing the encoding and routing the plurality of media contents over the IP network infrastructure. The module 210 can be in a master-slave relationship with the other modules, although other control relationships are also contemplated. In one embodiment, a separate controller can be utilized to implement each of the functions of the modules of device 200.
In another embodiment, the device 200 can receive feedback, such as through monitoring being performed at intermediary provider offices such as the central office and VHO. Based on the feedback, the device 200 can make adjustments to the plurality of media contents and/or the video transport stream, including adjusting FEC data in one or more of the media content streams, adjusting the resolution, and so forth. The present disclosure also contemplates the media distribution device 200 receiving the media content from various other sources, including over the network infrastructure or from a storage medium.
Other suitable modifications can be applied to the present disclosure without departing from the scope of the claims below. Accordingly, the reader is directed to the claims section for a fuller understanding of the breadth and scope of the present disclosure.
